Using the DeWalt DCD794D1 Drill/Driver is easy. First, charge the DCB203 20V MAX* 2.0Ah battery with the DCB107 charger. Then, insert the charged battery into the drill. Select the right bit for your job and secure it in the 1/2 in. ratcheting chuck. When drilling, hold the drill firmly and start at a slow speed, then increase as needed. Use the LED work light to see in dark or tight spaces. For safety, always wear safety glasses and avoid using the drill in wet conditions. To maintain your drill, keep it clean by wiping it down after each use. Store it in the kit bag provided to protect it from dust and damage. Also, make sure to charge the battery regularly to keep it in good condition.
